Looks like a pretty wide spread used modern led module shown in many cheap watches on ebay,but with a nicer case.Good to see one with a sapphire glass though,but a shame the module looks lcd back lit with those thick segments although they are led.

I have to agree that display design and button layout suggests the movement is the same as in several modern el-cheapo LED digital watches. The rate variations are within ± 60 s / month, according to the home page of G. Gerlach. That is substantially more than the ± 10-20 s / month one can expect from ho-hum quartz movements.

Hm. Dropping a suitable movement from Strikes and Spares into the Kosmonauta case is tempting, considering the possibility to obtain a watch which is nice from the inside out. I fear, however, that just because it would be a cool trick, it will turn out to be utterly impossible.
